IMPROVEMENT IN WATER-HEATERS.

Specification forming part of Letters Patent No. 159,103, dated January26, 1875; application filed i November 7, 1874.

To all whom it may concern:

Be it known that I, SAMUEL L. LATTA, of Ligonier, in the county of Nobleand State of Indiana, have invented a new and valuable ImprovementinWater-Heaters; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making apart of thisspecifleation, and to the letters and figures of referen ce markedthereon.

Figurel of the drawing is a representation of a horizontal section of mywater-heater. Fig. 2 is a longitudinal vertical sectional view of thesame, and Fig. 3 is a transverse vertical lsectional view.

This invention has relation to means for heating water forbuttershippers, for hotels, laundries, and other places where a largeamount of hot water is required.

The nature of my invention consists in a fire-chamber and smoke-flues,which are surrounded by water, the smoke-dues being arranged above thelire-chamber, and so formed as to cause the products of combustion topass forward and then backward before escaping through the exit-due. Italso consists in combining a supplementary Water-heater with the mainheater, for the purpose of keeping on hand a reserve of warmed water tosupply the place of that which is drawn out ofthe main heater, as willbe hereinafter explained.

In the annexed drawings, A designates the rectangular shell of theheater, and B the walls, which surround the iirechamber C. Between theupper wall oi' the fire-chamber C and a wall, a, is a horizontalliuc-space, which is divided by a partition, b, extending from the backwall, b', nearly to the front wall of the heater, thus forming two lues,c c', into the irst of which the products of combustion enter through anaperture, el', thence pass forward to the front of the heater, thencepass into ue c', and nally escape through a vertical pipe, D. The lowerend of the pipe D is secured permanently to the top wall of the ilue cat its rear end, and should the water in a space, d, descend too lowthere would be a liability of the joint between the pipe and said topwall leaking. To prevent this a cup,

7L, surrounds the lower end of pipe D, which will always contain Water,and keep the parts comparatively cool. The side, bottom, and.' backwalls of the fire-chamber, and the side, back, and top walls of thenue-space, are surrounded by water, which is contained in the space d,between said walls and the side, top, back, and bottom walls A of theheater. On top of the heater, and located at its rear end, is areservoir, G, of rectangular form, and provided with a hinged cover, f,and a stationary or ixed cover, f', as shown in Fig. 3. The plate whichforms the bottom of this tank is the top plate of the heater, andthrough this plate and the top plate or cover, f', the pipe D passes,and gives oii' its heat to the water contained in said tank. J is a coilof pipe, which is arranged in the tank or reservoir G, and whichcommunicates with the steam-space t' inside of the walls A, and alsowith the upper portion of the reservoir G. This pipe, except its upperend, is submerged in the water contained in the reservoir G, and thesteam which passes through it imparts heat to the water in thereservoir. K designates a feedpipe,`which passes through the top andbottom of the reservoir G, and in whch the feedpipe) a valve, r, isapplied, having a stem, r', attached to it, which valve is designed forclosing opening n, leading from the feed-pipe Kinto the space d, andalso into the reservoir G, as shown in Fig. 2. The front door, L, of thefire-chamber C is provided with a reg ister, Z, and the front end of theHue-space above this chamber is provided with a slide, m, which allowsaccess to the dues c c', for cleaning them out and for other purposes.

For the purpose of preventing the lire-chamber walls B from burning out,I employ a removable rectangular shell, B, which forms a lining for saidchamber and protects its walls.

-In front ci' the reservoir G a hole is made through the top plate ofthe heater, for the purpose of receiving a pot, N, in which to keepcoloring matter melted and ready for use in coloring butter.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the smoke-pipe D, lire-chamber C, and smoke-dues cc', nearly surrounded by water, the latter being arranged as described,so as to cause the products of perforated at n, and the valve 1",substantially combustion to pass forward and then baekas described.
